To ALL WHOM 1T MAY OONOEEN:

.Be it knownA that I, JEROME B.' SWEETLAND, of the cityof Pontiac, in theV count)T of Oakland, and in the State Aoi`lS'Iichi,fan, have invented Acertain new anduseful Iinprovements in Hooks; and 'do hereby' declare that the following is a full, clear, andexact description thereof, reference being had to the accompanying drawings, and to the letters of reference in arkedthereon.

The nature of my invention consists inthe general arrangement of a rafter-l1ook, so constructed that `in puttingit together there will be no holes to drill nor rivets to put in, the hoo'ks being cast with holes and rivets in them, Iand in the construction and application'ofa triangular slotted'plate with a hook attached to the saine.

In'order to enableothersskilled in the art to' make and use my invention, I will nowproceed to describe its constructionand operation.

In the'annexed drawings, forming part of this speciiication y t A A represent the two hooks, one of which is east with a recess or chamber on its front to admit the'other hook, so that when put togetherfthe'face side will beven. i i

A pin, a, is cast in the,centre of' the chamber, which iits into a. hole on the other'hook, by which. means the hooks are put together. o I Y, i l

.The upper ends of the hooksare also provided with pins or rivets, b b, vcast into them.

B represents a triangular slotted plate, ivhic'h has two side slots, c c, and 'one centre slot, el, which latter, however, is belowvthe side slotsi These slots it everthe three pins on the hooks A A, Vwhich are then riveted down, so that the plate Bwill slide up and down on the hooks, thereby opening or closing the same. i

Dn top of the plate B is a hook, D, to pass a rope over or to holdit by when used as an ice-hook.

x x represent the chamber formed in` the hook A. p l i Having thus fully described my invention, what I claim as new, and desire-to secure by Letters Patent, is-

1. The hooks A A, when castivith a chamber and with pins, a and b @substantiallyas and for the purposes herein set forth. p

EZ.. Thet'riangular plate B, provided withvhook Dv and slots 'c e and'oZ, substantially as and for the purposes herein set forth. I, i

3. Tllecombination'of the hooks A A, triangular' lslotted plate B .ring G, and hook D, constructed and operating substantially as andtfor the purposes herein set, forth. Y

In testimony thatfI claim tlie'foregoing 'Ihave hereunto set myhand, this lthvday of May, 1-868.

JEROME B. SWEETLAND.
